Answer:
Explanation:
The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms <u>only one strand is used to encode any particular gene</u>.
The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).
Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, <u>which produces an mRNA molecule that has the same sequence as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
The modern classification is based on a six Kingdom system-
<span>1- Animalia</span>
2- Plantae
3- Fungi
4- Protista
5- Archaea bacteria
6- <span>Eubacteria </span>
Cyanobacteria obtain their energy through photosynthesis
When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. In other words this occurs when heterozyhotes have increased fitness over both homozygotes. A good example is sickcle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
Answer:
1. <u>ntrdr</u> --><u> brken</u> --| <u>wag1</u> --> <u>Tail structures
</u>
2. Yes
Explanation:
(1) In this experiment three different genes are present;
1) Wag-1 - promotes production of tail structures
2) brkn gene - inhibits Wag-1 which leads to inhibition or inactive Wag1 gene and there is no tail formation.
3) ntrdr gene - stimulates the activity of brkn gene thus this in turn inhibits Wag-1 gene and results in inhibiting the tail formation.
(2) The ntrdr gene stimulates the brkn gene and active brkn gene inhibits the wag-1 gene. As we know Wag1 gene is essential for tail formation. on removing out ntrdr gene result in inactive gene brkn thus allows the expression of the Wag-1 gene allowing tail growth in dogs.
